A lot of people find the insurance model superficially appealing. But the maths is dreadful. Plus, the private equity vampires are moving in, pushing up costs and pushing down outcomes. I really can't imagine a worse model.
If the figures posted in Illinois are accurate (they won't be I wouldn't have thought) the result will not be people paying that. Most people get health insurance through employment, so it will push down wages - same as the NI hike is doing here. Most of the rest will just get lower levels of insurance, the effects of which won't be seen for some time.
